Which of the following does not apply to mutations?a. They occur to cause adaptive changes in response to the environment.b. They are usually either harmful or neutral.c. They are only inherited if they occur in a sperm or egg cell.d. They often occur when DNA is copied.
Background: In class we did a project about m and m’s and there ability to evolve and natural selection. (Yes I know they can’t actually evolve it was just used as a example in class) however I can’t figure out this question.
Occasionally a mutant may occur and produce a candy that is misshapen or Pointier or flatter than the rest. Often this proves to be a weakness, but a rare mutation may confer extra M&M durability. Other mutations in M&Ms could occur ( like ones that result in a new color). A mutant un you population represents a new _________.

A. A gene is the observable characteristics or traits
B. All are correct
C. Agene is a stretch of DNA that produces one or more genetic traits
D. A gene is the basic unit of genetic information for a specific trait

- Which of the following statements concerning genes are true? Select all that apply. A gene is a segment of DNA that determines a certain trait.A gene is a segment of DNA that determines a certain trait. An allele is a variation of a given gene. Genes contain information that codes only for proteins involved in the regulation of gene expression.Genes contain information that codes only for proteins involved in the regulation of gene expression. Genes are not responsible for the expression of traits.Genes are not responsible for the expression of traits. Allele variations are due to small changes in the nucleotide sequence within the gene that sometimes change the structure of a protein and ultimately its function.Allele variations are due to small changes in the nucleotide sequence within the gene that sometimes change the structure of a protein and ultimately its function.arrow_forwardWhich of the following would not be consistent with the ideathat a disorder has a genetic component?a.
